Has your vehicle seemed more sluggish than usual, such as lacking power when passing a slower vehicle or when trying to go up a hill? Has a dashboard light come on and you don’t know why? With winter here to stay for a while, it would be smart to schedule a car tune-up, which should include a diagnostic test.
So what does a car diagnostic test tell you? Today's modern vehicles have computer processors, microchips and sensors so if you need to know what is really going on inside your vehicle, a diagnostics test can reveal issues related with the engine and transmission, oil and gas tanks, exhaust system, and other systems.

It is probably to identify the cause of an issue speedily so that the right repair can be made before the issue gets bigger.
A typical tune-up checklist includes both preventative and restorative engine assessments, such as:
- Spark plugs--Spark plugs should have light tan or gray insulator firing noses so that it is correctly igniting the fuel? The wires should not be hard or cracked.
- Fuel pump and filter--make sure the filter isn’t clogged so the pump will function correctly.
